Aqueous enzymatic extraction of Moringa oleifera oil (original) (raw)

Extraction and characterization of oil from Moringa oleifera for energy purposes

Moringa and especially Moringa oleifera is worldwide valued due to its properties. One of the useful parts of the tree is the seed. The extraction of seed kernel oil from Moringa oleifera, Plain variety of Cuban origin is evaluated. The extraction percentage of oil is set as the dependent variable in the design of experiment. The studied factors (particle size, solvent-seed ratio and type of solvent interaction term) significantly influenced the dependent variable. The best condition for the extraction of oil was achieved with solvent-seed ratio (6:1), using hexane and milled seeds. The physicochemical characterization of the oil was in agreement with literature reports. Based on the profile of fatty acids, a predominant 74.72% of oleic acid was achieved, followed by palmitic, behenic and stearic acid (4.46%). The paper discuss about the potential of the oil for biodiesel production.

Oil Extraction Optimization and Kinetics from Moringa Oleifera ( PKM 1 ) Seeds

2013

Moringa oleifera, seed (PKM 1) was examined for extracted oil recovery under the different designed conditions using Central composite face centered design of Response surface methodology. The kinetics of extraction was investigated and its parameters were determined based on a second order model. The optimum conditions were found at 3.6 h reaction time, temperature, 67.84°C and solvent to solid ratio of 9:1. Among three process variables studied, solvent to solid ratio had the most significant effect on the oil percent followed by extraction temperature and time. The maximum extraction was found to be 33.30%. The characterization revealed that the oil had Iodine value 67.23, saponification value184.65, density 0.907 and refractive index 1.436 as respectively.

Optimization of Oil from Moringa oleifera seed using Soxhlet Extraction method

2020

Extraction of oil from Moringa oleifera seed using Response Surface Methodology (RSM) was investigated. Effects of three factors namely: sample mass, particle size and extraction time on the response, Moringa oleifera a volume extracted, were determined. The Box-Behnken design of RSM was employed which resulted in 15 experimental runs. Extraction was carried out in a 250 ml Soxhlet extractor with Hexane and Ethanol as solvent. The Moringa oleifera seed powder was packed inside a muslin cloth placed in a thimble of the Soxhlet extractor. The extraction was carried out at 60oC using thermostatic heating mantle. The solvent in the extracted oil was evaporated and the resulting oil further dried to constant weight in the oven. This study demonstrates that Moringa oleifera oil can be extracted from its seed using ethanol and acetone as extraction solvent. The optimum process variables for both solvent (ethanol and acetone) was determined at sample weight of 40 g, particle size of 325 μm ...

Extraction and characterization of Moringa oleifera Lam var. Supergenius seed oil from Cuba

La Moringa (M.) oleifera es altamente valorada a nivel mundial por las propiedades que posee. Una de las partes aprovechables del árbol es la semilla, ya que estas contienen entre un 30 y 45 % de aceite. El presente trabajo tiene como objetivo fundamental desarrollar la extracción de aceite a partir de las semillas de M. oleifera, variedad (var.) Supergenius de origen cubano mediante el empleo de hexano como disolvente. El porcentaje de extracción de aceite se estableció como variable respuesta en un diseño experimental del tipo factorial 2 2 , donde la relación soluto-solvente y el tiempo de extracción fueron los factores estudiados a dos niveles. Ambos factores influyeron de manera significativa en la variable respuesta, (con valores) asociados de P < 0,05. El modelo matemático obtenido explicó el comportamiento de la variable respuesta en 91,45 %. A partir del comportamiento del porcentaje de extracción de aceite con el tiempo de extracción, se propone un reajuste en dicho tiempo, garantizando un ahorro de energía. Las propiedades físico químicas y el perfil de ácidos grasos del aceite extraído están en correspondencia con reportes hechos para otras variedades de M. oleifera. Solamente existieron diferencias en cuanto al índice de acidez. El comportamiento reológico demostró que el aceite de M. oleifera es Newtoniano. ABSTRACT. Moringa (M.) oleifera is highly valued worldwide because of its properties. The seed is one of the usable parts of the tree because of its oil content between 30 % and 45 %. This paper aims to develop the oil extraction from seeds of M. oleifera, Supergenius variety (var.) of Cuban origin using hexane as solvent. The extraction percentaje was set as the response variable in the factorial 2 2 experimental design. The solute-solvent ratio and the extraction time were the studied factors at two levels. Both factors significantly influenced the response variable, with associated P values less than 0.05. The obtained mathematical model explained the behavior of the response variable at 91.45 %. An adjustment of the extraction time was developed in order to ensure energy saving. Physical and chemical characteristics and the fatty acid profile of the extracted oil agree with several reports of M. oleifera varieties. The difference is shown in terms of the acid content value. The rheological behavior of M. oleifera var. Supergenius oil was found to be Newtonian in nature.
